What up RIU fam , I have been vaping my wax out of a pen, but now I dont have any cartridges left and can't find any anywhere. Can anybody tell me a good website to go to to find some? 510 thread

Time to invest in a new pen...jk. Global Smoke or Wikipipes are good sites. Good luck. See my vape pen tech post if you want advice.

What kind of pen do you got ? Check out this Online Head Shop they have a ton of pens and other portable vaporizers if you can't find what your looking for email them they probably have it.
